An African-American student has been targeted by a vicious gang of teens who call themselves “Blackout” because they want to cleanse their predominantly white Long Island town of minorities, the teen says in a shocking, $5 million suit.

The family of 15-year-old Brian Orr, a freshman at Miller Place HS, leveled the suit against a 13-year-old student, the school district and several administrators, claiming officials did nothing when Orr complained.

Orr, one of only 10 black students at the school, says the gang scratched the n-word into his locker last year and repeatedly beat him in the hallways.

“They did what they had to do to make me feel ostracized from the rest of the school. It just got to be too much,” he said.

Last August, Miller Place made headlines when John White, 53, who is black, shot and killed his son’s white Newfield HS classmate, Daniel Cicciaro, 17, for harassing his son with a group of white friends at their home.

Orr’s lawyer, John Ray, said the alleged bullies in his suit and that incident probably “overlap.”

“This is an all-white enclave, and they were doing what they can to keep black people out of their community – but it’s going to stop here,” Ray said.

White is currently awaiting trial for manslaughter.

Orr’s family moved to Miller Place three years ago from high-crime Central Islip, seeking to put him in a better school.

The abuse began with name-calling and pushing in the hallways. At football practice, white teammates punched him in the stomach when he was at the bottom of a pile-on, the suit says.
